Forms

Form Classes

NetBox provides several base form classes for use by plugins.

Form Class	Purpose
`NetBoxModelForm`	Create/edit individual objects
`NetBoxModelCSVForm`	Bulk import objects from CSV data
`NetBoxModelBulkEditForm`	Edit multiple objects simultaneously
`NetBoxModelFilterSetForm`	Filter objects within a list view

`NetBoxModelForm`

This is the base form for creating and editing NetBox models. It extends Django's ModelForm to add support for tags and custom fields.

Attribute	Description
`fieldsets`	A tuple of two-tuples defining the form's layout (optional)

Example

from dcim.models import Site
from netbox.forms import NetBoxModelForm
from utilities.forms.fields import CommentField, DynamicModelChoiceField
from .models import MyModel

class MyModelForm(NetBoxModelForm):
    site = DynamicModelChoiceField(
        queryset=Site.objects.all()
    )
    comments = CommentField()
    fieldsets = (
        ('Model Stuff', ('name', 'status', 'site', 'tags')),
        ('Tenancy', ('tenant_group', 'tenant')),
    )

    class Meta:
        model = MyModel
        fields = ('name', 'status', 'site', 'comments', 'tags')

Comment fields

If your form has a comments field, there's no need to list it; this will always appear last on the page.

`NetBoxModelCSVForm`

This form facilitates the bulk import of new objects from CSV data. As with model forms, you'll need to declare a Meta subclass specifying the associated model and fields. NetBox also provides several form fields suitable for import various types of CSV data, listed below.

Example

from dcim.models import Site
from netbox.forms import NetBoxModelCSVForm
from utilities.forms import CSVModelChoiceField
from .models import MyModel

class MyModelCSVForm(NetBoxModelCSVForm):
    site = CSVModelChoiceField(
        queryset=Site.objects.all(),
        to_field_name='name',
        help_text='Assigned site'
    )

    class Meta:
        model = MyModel
        fields = ('name', 'status', 'site', 'comments')

`NetBoxModelBulkEditForm`

This form facilitates editing multiple objects in bulk. Unlike a model form, this form does not have a child Meta class, and must explicitly define each field. All fields in a bulk edit form are generally declared with required=False.

Attribute	Description
`model`	The model of object being edited
`fieldsets`	A tuple of two-tuples defining the form's layout (optional)
`nullable_fields`	A tuple of fields which can be nullified (set to empty) using the bulk edit form (optional)

Example

from django import forms
from dcim.models import Site
from netbox.forms import NetBoxModelCSVForm
from utilities.forms import CommentField, DynamicModelChoiceField
from .models import MyModel, MyModelStatusChoices

class MyModelEditForm(NetBoxModelCSVForm):
    name = forms.CharField(
        required=False
    )
    status = forms.ChoiceField(
        choices=MyModelStatusChoices,
        required=False
    )
    site = DynamicModelChoiceField(
        queryset=Site.objects.all(),
        required=False
    )
    comments = CommentField()

    model = MyModel
    fieldsets = (
        ('Model Stuff', ('name', 'status', 'site')),
    )
    nullable_fields = ('site', 'comments')

`NetBoxModelFilterSetForm`

This form class is used to render a form expressly for filtering a list of objects. Its fields should correspond to filters defined on the model's filter set.

Attribute	Description
`model`	The model of object being edited
`fieldsets`	A tuple of two-tuples defining the form's layout (optional)

Example

from dcim.models import Site
from netbox.forms import NetBoxModelFilterSetForm
from utilities.forms import DynamicModelMultipleChoiceField, MultipleChoiceField
from .models import MyModel, MyModelStatusChoices

class MyModelFilterForm(NetBoxModelFilterSetForm):
    site_id = DynamicModelMultipleChoiceField(
        queryset=Site.objects.all(),
        required=False
    )
    status = MultipleChoiceField(
        choices=MyModelStatusChoices,
        required=False
    )

    model = MyModel
